Primes

2015-06-28, post № 42

mathematics, programming, Pygame, Python, #generates, #generator, #prime, #prime generator, #prime layout, #prime numbers, #prime pattern, #prime patterns, #primes, #red, #white

Being fascinated with how prime spirals look, I tried another layout for primes. Starting at the upper left and writing out numbers like a normal text, starting at 𝟢 and coloring every prime number red, every other number white, this is the result.

It is interesting, that — like in prime spirals — the red squares form visible patterns. Randomly assigned squares would not as often form such patterns.

This program falls into the category ‘fancy, but not useful’. It basically starts with one circle, which spawns in new ones. The maximum number of circles is 𝟣𝟢𝟢, their color is a gray tone (rgb between 𝟧𝟢 and 𝟣𝟢𝟢).

FS Letters II

2015-06-21, post № 40

programming, Pygame, Python, #black, #dynamic, #file, #file check, #file system, #files, #filesystem, #fs, #red

Improving my first version — FS Letters — I changed a core behavior. Instead of going through the whole file system, saving it, interpreting it and then displaying it, I now went for a dynamic approach. As the filesystem gets checked (𝟨𝟢 times per second), the screen is also updating. This makes for both a more efficient (no freeze!) and a much nicer program. If the program is done checking the file system, the text ‘done’ will appear in the screen’s caption.
